lucasj12 Report post Posted March 24, 2018 My AC/Heater fan works intermittently. If its not working and I drive long enough, it will eventually come on but that may take 15-30 minutes. I've seen several topics on this but none with exact symptoms so not sure if it is the motor (doubt it since it will eventually work), the resistor, or the controller. Thanks!
